Charles lost control going out of bounds, took a bad step and wobbled on his leg before landing on the Lions mascot.

The Chiefs announced that his return is questionable.

Also questionable? The Chiefs chances of succeeding in what already appears to be a snakebitten season. They've lost tight end Tony Moeaki and safety Eric Berry for the season, and if the Charles injury is serious, an offense that hasn't really been able to get rolling is going to struggle even further.

It's probably also worth noting that the Chiefs did their best to hand the Lions an early score on Sunday with some penalties, and even though they picked Matthew Stafford early, they gave the ball back on a fumble in that same play. It's quite the cluster for Todd Haley's squad.

The potential for a serious injury to Charles is the most devastating blow yet, though. Despite the frustrating lack of carries, he's what makes the KC offense go, and without him, it's quite possible that KC could be stuck in reverse all season.
